They could be large or small and may cover large areas of the body. Small congenital nevi are 1.5 cm in size and the large ones measure 20 cm or more in size at birth. The aim of the plastic surgery is to remove the mole fully or to the maximum possible extent.

The nevi occur sporadically and are highly unpredictable on when it will occur. Small nevi are noticed in one in a hundred children whereas the big nevi occur in one in twenty thousand births. These moles are black in color. It can also be raised and have excessive hair on it. Since the hair growth is common, they are often referred to as giant nevi. Though the nevi can appear in any part of the body, they mostly appear on the abdomen, back, hips, and butt. Scalp and the face are also prone to nevi.

The child often suffers fits and seizures or other neurological problems. MRI scan will help detect it. The risk of congenital nevi getting malignant is high in the lifetime of the child. For small and medium-sized congenital melanocytic, the risk is very less – as low as 1%.

For giant nevi, the risk rate is 5-10% over the child lifetime. When the child reaches puberty age, the situation might worsen due to thickening or ulcerations of the lesion. Though there might be an urgent necessity for the removal of the nevi for medical and cosmetic reasons, the large nevi cannot be removed at once for the healing has to be over on the excised areas. Nowadays, many ways are present to close the surgical wound with tissues created by the removal of nevi. Treatment of the nevi depends on the size of the nevi, age, location, and the danger of it becoming malignant.
